I want to explore attending an American university. I already have a Canadian business degree, but want to get masters or another degree in the US. Trying to research US universities seems intimidating

I don't belong to Bill Gates family or any king, so I want to study somewhere where living costs and tuition are cheaper

I'm already pessimistic that high tuition and living costs will prevent me from studying in the US, but maybe someone has some advice. In the meantime I'm researching, but please share what you know.
